Random Shape Generation

[prashantcgi]

Hi Everyone!!

 

I want to make some random shape generation from one polygon geometry.

 

That is a polyon geometry changing shape into a new geometry randomly. Keeping number of points same all the time.

 

Any guys have any suggestion related to approaching this task please help.

 

If you have any reference or any sample file plz let me know.

 

please check the attached image.

 

Thank you

That seems pretty simple, with just those parameters. But the shapes you drew are more complicated than that.

Here it is in 3 SOPs. Start with a grid, add a sort sop and in that randomize the primitives based on the frame number, then add a blast SOP and delete non selected with 0-10 primitives if you want 11 polys.

 

What it looks like you drew is more like 4-5 segmented lines radiating out from a center. Each line randomly rotates. Then all the points are fused on a grid. Squares, the size of the grid, are copied to each point. And bingo. But that's going to vary the number of points.

Hi, you can use grid snaping in fuse sop. But it not always work as expected...

On second thought you can also animate a Mountain SOP after a poly Circle, just set the normals to the transform position.

Thanks Kleer!

i tried your method , the problem is it gives seperate faces and in some randomization steps they are completetly apart from each other which is not solving my objective.

This is kind of helpful!!! Still thinking whats the bestway to achieve this.

 

The good part of your method is that the point number remains same.

Maybe you could draw some shapes for me that demonstrate the qualities you're looking for? The ones you originally gave don't have the same point count. That's if you could the points as they align to a grid or just the 90 degree corners themselves. Or can you tell us what you're using it for? It's a little hard just to guess at your constraints. I'm totally happy to help, I just need to know what you need

Hi Kleer!

 

please check the attached image.

 

These shapes are all revolving in circle with sweep on it

Ok, I think I see how you're constraining your randomness.

 

Here's a shot. It's easier to show than tell. You'll just need to be careful of the fuse SOP because if your source points are too close to each other you'll lose the same point count. So, don't randomize your points further than half their starting distance. Cool?

 

If you need thin flat edges like your drawings you'll want to start with a modified circle, flattening one of the side. Try playing with the normals too.
